Description

Insulating panes with heat-protective insulating panels {INSULATING GLAZING WITH THERMAL PROTECTION INSULATING PANEL}

The present invention relates to an insulating glazing with a thermally protective insulating panel, a process for its manufacture and its use.

The thermal conductivity of glass is about 2 to 3 times lower than that of concrete or other building materials. Therefore, the greatest part of the building heat loss is through the exterior pane. This effect is particularly pronounced for high-rise buildings with partial or total glass facades. Insulating panes are an important clue to the solution. As the demand for higher raw material prices and stricter environmental protection regulations is increasing, the field of building structures without insulating glazing can no longer be imagined. As a result, the insulating glazing takes up a large part of the outer pane. Insulating panes generally comprise at least two panes of glass, polymeric material or polymer. These plates are spaced apart from each other by a gas or vacuum space defined by a spacer. The thermal insulation performance of insulating glazing is certainly high compared to single flat glass and can be further increased and improved for glazing with three layers of glazing or special coatings. In addition to the important properties of insulation, optical and aesthetic features play an increasingly important role in the field of architectural glazing.

In particular, in buildings with large area exterior glass facades, the thermal insulation effect does not only play an important role in terms of cost. The thermal insulation effect of very thin glass is generally lower than that of stone, so improvements are needed in this field. In order not to undermine the overall impression of the building, the use of a combination of stone and glass elements with good thermal insulation is infrequently used in most cases. One possible solution is an insulating glass plate in which an insulating member is arranged in the interface space of the glass plates. The heat insulating member includes various heat insulating materials and heat insulating materials. Often the insulation is packed in airtight and wet films. Subsequently, the entire heat insulating member is degassed. Such a thermal insulation member exhibits a significantly lower heat transfer compared to purely insulating glazing. In particular, in areas where transparency of the insulating glazing is not needed, the insulation of the building can be significantly increased without interfering with the overall impression of the facade.

However, inserting the insulating member into the insulating window pane is not easily achieved. Insulating glazing is often not completely filled with insulating members, resulting in empty space. This empty space is due to the dimensional tolerance, or the use of a plurality of insulating members in one insulating glazing. In particular, since the relatively wide external facade member requires a plurality of heat insulating members, the formation of an empty space is almost inevitable.

Along with insulation, sound insulation plays an increasingly important role. Primarily, street noise caused by increasing traffic has a negative impact on the quality of life and living in buildings. Like the thermal insulation effect, the sound insulation effect of the glass plate is definitely lower than that of brick or concrete.

DE 40 29 405 A1 discloses the structure and composition of a thermal insulation member. To this end, the powdered or fibrous material is filled into the microporous covering and dried. The microporous covering is then placed in an airtight and wet film and, if appropriate, degassed.

DE 43 19 763 A1 discloses a degassed non-translucent multilayer plate insulating glass panel. The interface space of the window plate is filled with microcrystalline or nanocrystalline powder and then degassed.

DE 43 39 435 A1 discloses non-transparent multilayer board panels for building facades, intermediate walls and cold rooms. At least one plate-shaped outgas is arranged inside the insulating pane.

DE 100 34 764 A1 discloses panels with inward and outward windows and watertight, steamtight and hermetic edge combinations. The interfacial space contains adiabatic powder disposed in a degassed sack.

It is an object of the present invention to provide an insulating glazing having both thermal insulation and sound insulation effects and having properties comparable to structural members of stone, gypsum or concrete.

The object of the invention is achieved according to the invention by the acoustic-damping insulating pane as claimed in claim 1. Preferred embodiments are claimed in the dependent claims.

A method for producing an acoustically-damped insulating pane according to the invention and its use is claimed in the other claims.

The acoustic-damping insulating pane according to the invention comprises at least one first and second plates. Peripheral spacers are disposed between the first and second plates. The spacer preferably comprises a hollow space. The hollow space of the spacer preferably comprises a desiccant, particularly preferably silica gel, CaCl ₂ , Na ₂ SO ₄ , MgSO ₄ , activated carbon, silicates, bentonite, zeolites and / or mixtures thereof. The desiccant is preferably arranged to allow gas and moisture exchange with the atmosphere inside the insulating pane, but the material is fixed without flying. This may preferably be done by enclosing the desiccant in air and moisture permeable polymer films or micro-mesh nets. The plate preferably contains flat glass, float glass, quartz glass, borosilicate glass, soda lime glass and / or mixtures thereof. The plate may also comprise a polymer such as polycarbonate or polymethyl methacrylate (Plexiglas). The seal seals the external space, gap or connection between the first plate, the spacer and the second plate. The first and second plates can have the same or different dimensions. In a preferred embodiment, one of the two plates can be designed as a laminated glass plate to be a three-layer pane as a whole. In addition, both plates may be designed as laminated glass plates to form four-layered glazing. A vacuum insulation panel is disposed between the first plate and the second plate. The vacuum insulated panel includes fibrous or powdery substrates that are packed and degassed in hermetic and wet films. Examples of powder substrates are shown, for example, in DE 4029405 A1. Between the first plate and the vacuum insulation panel (on the surface of the vacuum insulation panel or the plurality of adjacent vacuum insulation panels), an acoustic insulating plate is arranged two-dimensionally or flatly. The sound insulation board preferably comprises a sound insulation polymer plate, the thickness of the plate being at least 50 mm and the sound absorption coefficient being at least 0.5 (measured at 600 Hz to 4000 Hz, according to ISO-10534-2).

The sound insulation board is also preferably arranged between the second plate and the vacuum insulation panel, between the spacer and the vacuum insulation panel, and / or between the spacer and the vacuum insulation panel. The sound insulation plate fills and covers all of the outer surface of the vacuum insulation panel for the plate or spacer. By filling the interfacial space to the maximum, the sound insulation and thermal insulation effects are significantly increased.

The sound insulation board is preferably 0.5 mm to 5 mm in thickness. The thickness of the sound insulation board is preferably determined based on the size of the interface space between the vacuum insulation panel and the first or second plate.

The fillers preferably have an average diameter of 10 nm to 100 μm. The narrow size distribution of the filler and the homogeneous geometric shape improve the thermal insulation effect of the vacuum insulation panel.

The vacuum insulation panel is preferably shrink-wrapped in airtight and wet film. Leakage in the vacuum insulation panel can cause a decrease in the insulation effect.

The seal is preferably a polymer or silane-modified polymer, particularly preferably an organic polysulfide, silicone, RTV (room vulcanized) silicone rubber, HTV (hot vulcanized) silicone rubber, peroxide vulcanized silicone rubber, and / or addition Vulcanized silicone rubbers, polyurethanes, butyl rubbers, polyacrylates, and / or mixtures or copolymers thereof.
